A bundle project producing JAX-RS RI bundles. The primary artifact is an "all-in-one" OSGi-fied JAX-RS RI bundle (jaxrs-ri.jar). Attached to that are two compressed JAX-RS RI archives. The first archive (jaxrs-ri.zip) consists of binary RI bits and contains the API jar (under "api" directory), RI libraries (under "lib" directory) as well as all external RI dependencies (under "ext" directory). The secondary archive (jaxrs-ri-src.zip) contains buildable JAX-RS RI source bundle and contains the API jar (under "api" directory), RI sources (under "src" directory) as well as all external RI dependencies (under "ext" directory). The second archive also contains "build.xml" ANT script that builds the RI sources. To build the JAX-RS RI simply unzip the archive, cd to the created jaxrs-ri directory and invoke "ant" from the command line.

There is a newer version: 3.1.9

/**
 * Defines the default value of request meta-data that is bound using one of the
 * following annotations:
 * {@link javax.ws.rs.PathParam},
 * {@link javax.ws.rs.QueryParam},
 * {@link javax.ws.rs.MatrixParam},
 * {@link javax.ws.rs.CookieParam},
 * {@link javax.ws.rs.FormParam},
 * or {@link javax.ws.rs.HeaderParam}.
 * The default value is used if the corresponding meta-data is not present in the
 * request.
 * 
 * If the type of the annotated parameter is {@link java.util.List},
 * {@link java.util.Set} or {@link java.util.SortedSet} then the resulting collection
 * will have a single entry mapped from the supplied default value.
 * 
 * 
 * If this annotation is not used and the corresponding meta-data is not
 * present in the request, the value will be an empty collection for
 * {@code List}, {@code Set} or {@code SortedSet}, {@code null} for
 * other object types, and the Java-defined default for primitive types.
